Gobi - Khongoryn Els - Calm before the storm (Mongolia)

We had just climbed one of the highest sand dunes of Khongoryn Els in the Gobi desert and we were on our way back to the ger of the nomadic family where we were staying. However, it was becoming colder and the sky became more threatening. My friends and a dog of the nomads looked like dark silhouettes against the bright light in the distance. So I quickly shoot this photo. 10 seconds later we got an cold rain shower.
